That's what I have in mind -- limited to a few unique DOffs, essentially like "trophies". As far as making 3D models, I don't think it should be that difficult, The 2D portraits already look like characters made in the Character Tailor. For all I know, that's how they make the portraits -- just add PhotoShop.

Sure for the regular Doffs, but still that takes work. The unique ones like the ultra-rare Xindi Doffs would require new art resources I think. These are the ones that players would want to brag about since there is no current way to show what unique doffs you have to other people without emailing a photo to another player.
